User Story

When Flash is set as click-to-activate for a site:
WHEN an <object> with Flash type has fallback content
AND WHEN that fallback content does not heuristically match an "install Flash" message
AND WHEN the fallback content is not a single <embed> element.
THEN Render the page with the fallback content instead of showing the Flash click-to-play message
Heuristic details, subject to validation:
If the fallback content contains the words "install" and "Flash", in common languages, then it is a install-Flash message.
If the fallback content contains a link to anywhere within adobe.com, it is an install-Flash message.
This behavior must be instituted behind a feature pref.
While we still support other plugins, this change must not affect the use of any other plugin.

Please be sure to advise the docs team about any bugs related to this that will be of interest to web developers. I did not document the Flash hidden from navigator.plugins since it’s disabled by default now and things are up in the air on that, but be sure to put dev-doc-needed keyword on any bugs which are dev-facing. Thanks!
